Norcold "Li oP" error code

[JD51]

We have a 2017 Jayco Greyhawk. On the last trip we had this code pop up just before leaving town. Used the magnet to reset but it came on a few times while we were out. Shut Frig off for a few minutes and then restarted to clear code. When leaving we switched to propane but code came back on. Any ideas? We have a 1210T Norcold 12 cu ft. When I checked their website I saw a recall but our model/Serial# not part of it.

The part is "Norcold fridge over-temp board, #634677 Revision E"

Looking for any suggestions to fix. Thanks in advance for any help!
